Europe total 219.885 20.581.236.000 Kwh/year= 20.581 GWh = 2,970 AKW
USA 112.000 10.483.200.000 Kwh/year
Japan 46.782 4.378.795.200 Kwh/year
Total 378.667 35.443.231.200 Kwh/year (EU,USA,Japan) = 35.443 GWh = 5,115 AKW
Europe total 219.885 Million households
Take all households and take it that each household has at least one vacuum cleaner, then:
219,885 Million households x 1 vacuum cleaner x 1 hour/week x 1800 Watt = 396 Million KW electricity usage = 396.000 Megawatthours = 396 GWh x 52 Weeks = 20.592 GWh/year = 297% of the years usage of the atomic power station Grafen Rheinfeld (6.928 GWh/year) = 2,97 AKW (atomic power stations)
If you replace all existing vacuum cleaners with the new 140 Watt vacuum cleaner system then you arrive at this calculation:
219,885 Million households x 1 Staubsauger x 1 hours/week x 140 Watt = 30,78 Million KW electricity usage = 30.783 Megawatthours = 30,7 GWh x 52 weeks = 1.596 GWh/year = 23,0% der years electricity usage of the atomic power station Grafen Rheinfeld (6.928 GWh/year). =0,230 AKW (atomic power stations)
Hereby, one can save in Europe:
18.996 GWH (Gigawatthours) = 2,74 atomic power stations (Grafen Rheinfeld).
Europa + USA + Japan total 378.667 Million households
Here, the total usage would be reduced to 2.756 GwH, with a total saving of 32.687 GWh = 4,72 atomic power stations Grafen Rheinfeld.
